Abstract
The efficiency and sample capacity of conical liquid chromatographic columns with 10 degrees opening angle were studied at different ratio of cross section areas of inlet to outlet (A(in)/A(out)) and column dimension. As the A(in)/A(out) ratio changed from 4 to 2.25, the reduced plate height (h) was reduced and the h value decreased 12% when the column dimension was scaled up proportionally because of relatively smaller dead volume on both end of the column. Compared to cylindrical columns having corresponding lengths and volumes, the conical columns with 10 degrees opening angle were superior in column efficiency, resolution and the maximum peak concentration at column outlet; the loadability of conical column was improved 30-40% on injection volume and 50-60% on sample mass, respectively, over cylindrical columns.

Abstract
A multidimensional heart-cutting reversed-phase HPLC separation approach, where two columns were operated independently via two six-port two-position switching valves, was employed in the isolation of a major bioactive found in the ethanol-water (80:20) crude extract of Clerodendrum floribundum. In this mode of operation, the specific productivity of the multidimensional approach under overload conditions was twice that of conventional gradient methods with the same loading factor. Isolated sample purities were greater than 99% with recoveries of 95%. The independent operation of each of the two columns employed in the multidimensional approach allowed the cycle time to be less than 7 min, compared to 23 min in the gradient elution single-dimension mode of operation.

Abstract
This paper describes the development of a portable, automated flow injection-chemiluminescence (FI-CL) analyzer incorporating on-line solid-phase extraction (SPE) for the determination of dodecylamine (detergent) in diesel fuels. The method is based on the peroxyoxalate/sulforhodamine 101 chemiluminescence reaction, with SPE required to remove indigenous compounds within the diesel fuel matrix that interfere with the CL response. The automated analyzer achieved a detection limit of 2.9 mg L(-1) and a linear range of 2.9-50 mg L(-1), which was suitable for determinations of dodecylamine at levels typically present in fully formulated diesel fuels (40 mg L(-1)). Analyses of base fuels from five different sources demonstrated that an automated FI-CL-SPE system could provide a portable instrument for monitoring the presence/absence of dodecylamine in diesel fuels.

Abstract
The behavior of a packing material (Luna C18 from Phenomenex, Torrance, CA, USA) was studied during the consolidation of a column bed under axial compression stress. The kinetics of this consolidation, the permeability and efficiency of the columns obtained, and the reproducibility of these column properties were measured under different conditions. The consolidation process and the column properties are considerably affected by the friction between the packing material in the bed and the column wall. Clear evidence of this wall effect was demonstrated. The apparent permeability of columns consolidated under the same axial stress increases with increasing column length. The apparent modulus of elasticity of the beds increases with increasing column length. The shear resistance between the packed bed and the column wall was measured for columns of different lengths. It increases rapidly with increasing bed length. The column efficiency for thiourea (unretained) and phenyloctane (retention factor, k' approximately 1) was much poorer after recompression than after the first compression. It depended little on the compression stress. The effect of the column length was small.
